Ошибка 3414 не запускается служба sql server

MS SQL Server is the most widely used database server and is also prone to many unexpected errors. One such error is SQL Error 3414.

The error occurs when the database fails to recover.

Here, at Bobcares we handle errors such as this regularly as a part of our Server Management Services.

Let us discuss the possible reasons and fixes for this error.

What causes SQL error 3414?

SQL Server Error 3414 occurs during start-up time while the recovery process for SQL database is not completed successfully.

We can identify the root cause of the error from the SQL error logs or from the event logs.

When a database fails to recover, an error like the one shown is present in the SQL error logs and event logs.

Error: 3414, Severity: 21, State: 1.
An error occurred during recovery, preventing the database 'database name' (database ID XX) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support)

There are multiple reasons for the database recovery to fail. We can identify the failed database from the error logs.

During the error, the database is automatically set to a suspect mode. As a result, SQL services stop as well.

The SQL services will not start until we resolve the error with the database.

Today let’s see how to fix it.

How to fix SQL error 3414?

The two main fixes for this SQL 3414 error are:

• Restore from backup
• Emergency repair method by DBCC CHECKDB

That is, we can fix this error either by restoring the failed database from the backup or repair the database from the emergency mode.

Let’s see how this works.

Restore from backup

This is the most recommended and simplest method.

We can restore the database from the Microsoft SQL management studio by following the steps shown:

• Open Microsoft SQL management studio.
• Connect to the database instance and right-click on the database.
• Click on tasks and then click on restore.
• Click on the device button and click add.
• Now, browse the database backup location and select the file.
• Next, click ok.
• Once the window closes verify the details and finally click ok.

After a few minutes, the database restores and a successful message pops up.

Emergency repair method by DBCC CHECKDB

This is the next option in case the backup of the database is not available. This is one of the best methods to retrieve the data of the database.

DBCC CHECKDB is the T-SQL command that checks the logical and physical integrity of all the objects in the specified database.

Currently, the affected database will be in suspect mode. To retrieve the database we need to change the database to emergency mode.

Use the below commands to set the database to emergency mode.

EXEC sp_resetstatus ‘database name’;
ALTER DATABASE 'database name' SET EMERGENCY

Then, perform the consistency check in the database using:

DBCC CHECKDB (‘database name’)

Next, use the repair command to repair the database.

DBCC CHECKDB (‘database_name’, REPAIR_ALLOW_DATA_LOSS)

The table causing the database error gets removed when the command is executed.

SQL databases will be accessible now.

Now the user needs to verify the missing tables in the database and manually add it in the database.

Once the database check is complete, start the SQL services back.

Conclusion

In short, the SQL 3414 error mainly occurs due to database recovery failure. Today, we discussed in detail the two ways by which we can bring back the database in order to fix this error.

SQL Server Error 3414 – What Does It Mean?

SQL error 3414 occurs when the database fails to recover. The status of the Database in SUSPECT Mode after the occurrence of the error. The effect of this error is reflected in SSMS and in the column of sys.databases.state_desc. If the user tries to connect the database in this error, then it will result in SQL database suspect error 926.

When a line in the server log file has the same value of SPID, SQL Server error 3414 is encountered. For example, sometimes the recovery failure is due to checksum error when trying to read a log block to roll forward a transaction.

It is necessary to know the root cause of the error. One can examine the root cause of this error by checking the ERRORLOG. This helps the user to resolve the issues by applying the appropriate method. Once the user is aware of the cause that leads to ‘Windows could not start the SQL server on Local Computer error code 3414’ then he/she can adopt healthy measures to prevent the error Accordingly.

Troubleshoot Microsoft SQL Error 3414

The user can implement different methods to resolve ‘SQL Server Service not starting error 3414’. However, restoring from a good backup is the most suitable option to resolve this issue. If the user is not able to recover from a backup then he/she can adopt the following methods given below:

• Using Emergency Repair method provided by DBCC CHECKDB
• Try to copy data from one database to another database
• Use automated solution – SQL Recovery

#Method 1: Use Emergency Repair provided by DBCC CHECDB

Executing DBCC CHECKDB command should be the first priority of the user. This method will help the users to get the database in online and accessible mode. However, due to the recovery failure, the consistency of the transactions is not guaranteed. Therefore, it is nearly impossible to track the transactions, that should be rolled back or rolled forward.

Now, you have to use DBCC statements with REPAIR_ALLOW_DATA_LOSS option. This option will eliminate all the damaged and inconsistent data and will result in the physically consistent database. To run the consistency check, run the command given below:

ALTER DATABASE database_name SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
DBCC CHECKDB(database_name,REPAIR_ALLOW_DATA_LOSS)
GO

If you are not able to fix the SQL Server error 3414 using the above method then switch to the other methods given below.

#Method 2: Copy or Move Data to Another Database

Try to copy the data into another database, this will help you to get access to the database. Before doing this task, you have to put the database in emergency mode by following the below-mentioned command.

ALTER DATABASE database_name SET EMERGENCY

As we all know, Microsoft released MS SQL Server 29 years ago i.e. SQL Server 1.0 and for ages, it has reached many milestones with its ease of use and security. It has grabbed its own space in online markets with lightning speed over the years. The latest version was released in 2017 i.e. SQL Server 2017 which also supports Linux platforms as well such as Red Hat Enterprise Linux, Ubuntu, SUSE Linux Enterprise & Docker Engine.

MS SQL Server is a management system for storing and extracting data from the connected application. Though the most widely used secure and safe database server, it is also prone to unexpected errors. One such error is “SQL Error 3414” –

SYMPTOMS of the Error 3414:

The error is caused when the SQL Server service does not start during login or startup of database recovery. Hence, the database fails to retrieve causing MSSQL error code 3414.

The extended form of the error written to ERRORLOG or Windows Application Event Log with EvenetID-3414 with SQL Server is as follows:

Usually, an error that precedes Error 3414 in the ERRORLOG or Event Log is the reason for SQL database recovery failure.

Also, the status of the database is set to SUSPECT. The SUSPECT status is reflected in SQL Server Management Studio and sys.databases.state_desc. If you try to operate the database in this state you might encounter “SQL suspect database error 926” as follows:

Understand the Primary Cause of the Error 3414

The basic cause of the occurrence of error 3414 is due to the same SPID value in the server log file with the failure in the recovery of the database file. Go through the following checksum error that occurred during the time of the “read page” operation in the database to roll forward a transaction.

Resolution to Fix “Error Code 3414” in SQL Server?

The best possible solution to resolve the SQL Server error 3414 is to restore the database from a backup (if available) using SQL Server Management Studio. It is a good practice to take timely backups for handling unexpected disastrous situations. But, there are times when it is not possible to recover from a backup of the database or incomplete data is restored from your available backup. Here are the following methods to fix the error:

Method 1: Use DBCC CHECDB for emergency repair

Executing DBCC CHECDB should be your first step to get back the database to running state.

DBCC CHECKDB
[ ( database_name | database_id | 0
[ , NOINDEX
| , { REPAIR_ALLOW_DATA_LOSS | REPAIR_FAST | REPAIR_REBUILD } ]
) ]
[ WITH
{
[ ALL_ERRORMSGS ]
[ , EXTENDED_LOGICAL_CHECKS ]
[ , NO_INFOMSGS ]
[ , TABLOCK ]
[ , ESTIMATEONLY ]
[ , { PHYSICAL_ONLY | DATA_PURITY } ]
[ , MAXDOP = number_of_processors ]
}
]
]

However, it the best method but transactional consistency is not guaranteed since recovery failed. There are no ways to find out which transactions were rolled back or rolled forward and not allowed due to recovery failure.

Method 2: Copy Entire (healthy or recoverable data) Database to another Database

If the first workaround method fails to work, then you must try to copy all the possible data that is in the healthy or recoverable state to another database. To do this, set the database in emergency mode with the help of the given command:

ALTER DATABASE <dbname> SET EMERGENCY

After setting emergency mode, you can try to copy or move all the data to another database.

Resolve with Automated Method – SQL Database Recovery

In case the above-mentioned methods fail to fix and recover the database, then we recommend you immediately choose SQL Database Recovery software. This SQL Recovery is the most trustworthy software that serves the purpose of resolving SQL Server error code 3414. The software is specially designed for the recovery of corrupt and inaccessible SQL database files of any SQL server version.

Conclusion

In this blog, we have completely analyzed one of the common SQL Server errors which occur during the database recovery. Along with symptoms, primary cause, three potential manual solutions, a complete SQL Database Recovery software for quick and fine recovery of data from corrupted SQL Server database file is proposed in the end.

SQL Server goes into whole recovery phase on each time login and sometimes there are complaints by the users stating crash down of the server with an error like this.

It can occur even while applying any functions or manipulations and when the SQL Server service is not started with the login on the SQL Server. Here, as we can see in the error message, the recovery failure occurred due to the service-specific error code 3414. In the Event Log, the reason behind this failure can be detected as it depends on the preceding error logs with log files having similar SPID value.

When user tries to roll forward a transaction log with read page operation on the database, the checksum error appears like this:

“2010-03-31 17:33:13.00 spid15s Error: 824, Severity: 24, State: 4.
2010-03-31 17:33:13.00 spid15s SQL Server detected a logical consistency-based I/O error: (bad checksum). It occurred during a read of page (0:-1) in database ID 13 at offset 0x0000000000b800 in file ‘C:Program FilesMicrosoft SQL ServerMSSQL10.SQL2008MSSQLDATAmydb_log.LDF’. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
2010-03-31 17:33:13.16 spid15s Error: 3414, Severity: 21, State: 1.
2010-03-31 17:33:13.16 spid15s An error occurred during recovery, preventing the database ‘mydb’ (database ID 13) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support”

With the failure of database recovery and onset of this error, the database goes into SUSPECT mode which is visible against the server database name in the SQL Server Management Studio.

If any user tries to use the database in this SUSPECT mode, he has to encounter the progressive error stating –

“Msg 926, Level 14, State 1, Line 1
Database ‘mydb’ cannot be opened. It has been marked SUSPECT by recovery. See the SQL Server errorlog for more information”

So, there is a need to fix this error code 3414 issue to get back the normal database functioning once again. As we know handling the SQL Server, its features and functions is a bit complex task. So, there is a need of technical knowledge for performing manual solutions which might include running SQL Server queries to repair or restore the SUSPECT database in SQL Server; you can also restore SQL Database with a different name.

As recommended by Microsoft itself, we are explaining some of the workable manual methods for fixing or resolving this SQL Server error. Keep following carefully these methods and use them accordingly.

1st Method: Go for Restoring SQL Data through Recent Database Backup

If SQL Server user is in good practice of taking regular backups of their SQL database file and need to access it urgently. Then, restoring data from backup is a nice and easy choice. Perform these easy steps in order to restore your database from backup file.

1. Launch the Microsoft SQL Server Management Studio as an administrator.
2. Go to Object Explorer panel on the left, make connection to SQL Server Database Engine, select it and expand.
3. Now select Databases option and right-click on it. Select Restore Database option from the list.
4. Next, on the General page, under Source section, choose the Database option and add the recent database backup file from the list.
5. The restore process will get started and complete based on the database size.
6. Restart the SQL Server and check for the error code oncoming again.

For users who don’t have any backup file for the SQL database, we have other manual solutions as well.

2nd Method: Perform Emergency Repair Solution via DBCC CHECKDB

SQL Server provides its users certain SQL Query and commands to check upon the integrity of the SQL Database. DBCC CHECKDB command is helpful in checking the database in terms of accessibility and fixing related issues. Databases should be put in emergency mode as transaction consistency (no tracking of transaction roll back and forward) is not possible with DBCC command alone.

To put the databases in emergency mode, execute this command in New Query in SQL Server Management Studio run as administrator on your SQL system.

EXEC sp_resetstatus ‘db_name’;
ALTER DATABASE db_name SET EMERGENCY

Provide SQL Server database name at the required locations in the commands.

Perform integrity check on the SQL Server database using the following command.

DBCC CHECKDB (‘database_name’)

After checking the consistency of the database, the minimal repair recommendation would display. For that, to allow repair, set the database to single user executing this command.

ALTER DATABASE database_name SET SINGLE_USER WITH ROLLBACK IMMEDIATE

Run the DBCC repair command as follows with introduction of “Repair Allow Data Loss” feature.

DBCC CHECKDB (‘database_name’, REPAIR_ALLOW_DATA_LOSS)
After this repair, users can set the database to multi-user for connections using this command.
ALTER DATABASE database_name SET MULTI_USER
And if the steps failed to repair the SUSPECT database, try copying out data from the database to a new database after putting it back in emergency mode. It will let you access the database content.
EXEC sp_resetstatus ‘db_name’;
ALTER DATABASE db_name SET EMERGENCY

Exit the Microsoft SQL Server Management Studio. Now, restart the server and check if the issue is resolved.

What to do if this method did not work?

It is possible that simply executing DBCC CHECKDB command in emergency mode does not fix the error. You can use COPY OUT command to copy the whole database to a new database but needs to put the databases in the emergency mode using this command as used earlier.

EXEC sp_resetstatus ‘db_name’;
ALTER DATABASE db_name SET EMERGENCY

Note: SQL administrators can follow the online troubleshooting solutions provided in the Event Error Log itself.

How manual solutions are not completely reliable?

Restoring database manually from backup file does not ensure the complete backup of SQL database objects. It might include data loss or modification during the whole process. Also DBCC CHECKDB command is not helpful due to issues of transaction log files tracking as some or other manual errors can be expected even in the Emergency mode. All these tricks require good amount of time and efforts with some technical knowledge. So, limitations might hold back users and lead them to look for a better alternative.

Alternative Option – Third Party tool
